Patented Apr. 8, 1930 UNITED STATES CHARLES L. GOI-IMANN, on NEW ALBANY,iNDInNn, lrssreNon- T0 *GoHM-ANN BROS. AND KAHLER COMPANY, on NEWALBANY, INDIANA, A conroRATroN or INDIANA DOOR CONSTRUCTION FOR STOVECASIl l'G-S Application filed February 4, fate. serial No. ames.

This invention relates to stove casings or shells and more particularlyto the doors usually carried by the front panel thereof. So far as I amaware, stove casings of this general class have not heretofore beenprovided with sliding doors, such, by way of example, as the doorconstruction shown in Fig. 2 of the drawing.

The object of my invention is to provide an entirely new construction ofdoors for stove casings and the like, which is simple, efficient,economical to manufacture, easy to operate and when opened entirelydisappear behind the front panel of the stove casing. With that end inView, the invention contemplates the provision of sliding doors, locateddirectly behind the front panel of the shell or casing and which may befully closed, or fully opened, for the purpose of gaining access to thestove, mounted within the casing.

Another object of my invention is that when the doors are moved toopened position they do not extend outwardly from the casing but arehidden or concealed behind the casing and permit a maximum opening inthe casing.

The invention consists in the construction, combination, location andarrangement of parts, as herein set forth and claimed.

In the drawing:

Fig. 1 is a front elevation of a stove casmg equipped with my noveldoors, which doors are shown in the closed position;

Fig. 2 is a perspective view of the front panel of the stove casingviewed from the 111- side and which clearly shows the invention, one ofthe sliding doors being partly broken away to more clearly show oneopening in the front panel;

Fig. 3 is a vertical section of the front panel taken on a planecorresponding to line 33 of Fig. 1.

In the embodiment of my invention as illustrated and which shows apreferred construction, I provide a metal casing or shell 1, for heatingstoves and the like, and the invention has to do only with the frontpanel 2 of said shell 1. Generally, the front panel 2 ofthe casing 1 isprovided with a fuel opening 3 and an opening 4:, the latter being forthe purpose is closed by doors 7 and 8, which doors are l siidablymounted upon rods 9 behind panel 2.

Referring to the doors 5 and "'6, which are adapted to close the opening3', it will be clearly seen, by examination of Fig. 2, that said doorsare adapted to move in unison by their 9 connection with one anotherthrough chains 10. (his end of each of the chains f0 securely attachedto the upper *edge 5 of door =5 and the other end "of "each of thechains 10 is securely attached to the sides of dooi 6 any suitablemanner as, for er ample, by screws ll. Pulleys 12am rota'tably earnedlay-brackets 13, said brackets being Securely fixed to the upper edge offront panel 2 by bolts 14.

The chains 1 0 are adapted to be passed over the pulleys 1-2, as elem-1yshown in Fig. 2, and upper door 5 is provided with knobs or handles 15,as clearly shown in Figs. land 8.

The lower doors 7 and 8 are also slidably mounted upon rods 9 andarecon-nectedto one another by chains 16, whichcha ins are reoeived overpulleys 17, the said pulleys being rotatably mounted within brackets'18. The brackets 18 are rigidly attacli'ed to the inner-surface 2" offront panel 2 i'n any suitable manner and are provided with angular ears18 which ears are adapted to receive and support the lower portion ofrods 9. The upper end of, the rods 9 are received and supported by thebrackets The operation of my novel door construction is as follows:

Assume that doors 5 and 6 are in the closed position, as shown in Fig.1, thereby closing the opening 3 of front panel 2 and that the doors 7and 8 are also in the closed position, thereby closing the opening 4 insaid front panel 2. To open the doors 5 and 6, thereby uncovering theopening 3, simply grasp knobs 15, mounted upon upper door 5 and pushupwardly towards the top 19 of casing or shell 1. This upward movementof the knobs 15 causes door 5 to be slid upwardly on the rods 9 and thedoor 6 to be slid downwardly upon 5 rods 9 towards the bottom 20 ofeasing 1. To

close the doors 5 and 6, simply pull downwardly on knobs 15, therebysliding the door 5 downwardly upon rods 9 and as the door 5 is sliddownwardly on rods 9 the door 6 is 10 simultaneously drawn upwardly uponsaid rods 9 by chains 10.

The doors 7 and 8 are operated in the same manner as the doors 5 and 6.To open the doors 7 and 8, simply grasp knobs 21 and pull upwardlytowards the top 19 of easing 1. To

closethe doors 7 and 8, simply push downwardly on knobs 21, therebylowering the door 7 and simultaneously raising the door 8, thusclosingthe opening 4 in the front 20 panel 2 of easing 1.

It will be understood that certain changes and modifications of theinvention can be .made without departing from the scope or spiritvthereof as defined in the claims.

,VVhat I claim as new and desire to secure by Letters Patent is:

1. In a stove casing having a door opening therein, a pair of doorsadapted to close said opening, a pair of rods mounted adja- V cent saidcasing upon which said doors are slidably mounted, a pulley adjacent thetop of each rod, a pair of chains each connected to said doors,respectively, and passing over said pulleys, respectively, and meanswhereby said doors may be drawn to open or closed position as desired. 7

2. The combination of a stove casing having an opening therein,vertically arranged doors slidably mounted behind said casing andadapted to close said opening, and means operatively connecting saiddoors with each other whereby they are adapted to move in unison and inopposite directions.

3. In combination with the front panel of a stove casing having aplurality of openings therein, a pair of vertically arranged doorsadapted to close,each opening, means for sliding each pair of doorscomprising a chain fastened to the upper door, a pulley over which saidchain is passed, the other end of said chain being attached to the lowerdoor, and a vertically disposed guide rod adapted to pass through all ofsaid doors to keep them in alinement.
